Abstract
Abstract A generator capable of producing electric current includes at least one stationary permanent magnet or electromagnet aligned with at least one stationary core of non-permanent magnetic material provided with an induction field coil winding. The poles of the aligned magnet and core face one another on opposite sides of a magnetic flux field suppressor in the form of a rotary disc. This disc has alternating equal width sectors of a magnetic material and sectors of a non-magnetic material, the former being comprised of a plurality of magnetic sheets interleaved with thin strips of non-magnetic material.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
185 words
An electric generator comprising: at least one stationary magnet and at least one stationary core of non-permanent magnetic material provided with induction field coil windings and disposed in alignment with said magnet with poles facing one another, a magnetic flux field suppressor movably mounted between said magnet and said core, said suppressor comprising a rotary circular disc having first portions forming alternate sectors of stacked non-permanent magnetic sheets interleaved with thin layers of non-magnetic material, the remaining portions of said disc being sectors of non-magnetic material, said sectors being in alignment with said facing poles, means rotating said disc so that, upon rotation of said disc, the magnetic flux lines passing between said aligned magnet and core pass through said remaining portions and through said core and back to said magnet and are redirected and focused by said first portions as said flux lines pass along said sheets to thereby alternately induce and electric voltage and current in said coil as the flux field of said magnet is alternately allowed to pass through said core via said remaining portions of said disc during rotation thereof.
Claim 2
Dependent Claim
185 words
An electric generator comprising: at least one stationary magnet and at least one stationary core of non-permanent magnetic material provided with induction field coil windings and disposed in alignment with said magnet with poles facing one another, a magnetic flux field suppressor movably mounted between said magnet and said core, said suppressor comprising a rotary circular disc having first portions forming alternate sectors of stacked non-permanent magnetic sheets interleaved with thin layers of non-magnetic material, the remaining portions of said disc being sectors of non-magnetic material, said sectors being in alignment with said facing poles, means rotating said disc so that, upon rotation of said disc, the magnetic flux lines passing between said aligned magnet and core pass through said remaining portions and through said core and back to said magnet and are redirected and focused by said first portions as said flux lines pass along said sheets to thereby alternately induce and electric voltage and current in said coil as the flux field of said magnet is alternately allowed to pass through said core via said remaining portions of said disc during rotation thereof.
Claim 3
Dependent Claim
88 words
The electric generator according to claim 1, wherein a plurality of said magnets are equally spaced apart in a circular array, a plurality of said cores being likewise equally spaced apart and respectively in alignment with said magnets, whereby, upon rotation of said disc, the magnetic flux lines pass between said aligned magnets and cores through said remaining portions and are redirected and focused by said first portions as said flux lines pass along said sheets to thereby intermittently induce an electric voltage and current in said coils.
Claim 4
Dependent Claim
65 words
The electric generator according to claim 2, wherein said magnets and said cores are partially encased within shells each comprised of a plurality of non-permanent magnetic sheets interleaved with thin layers of non-magnetic material, the ends of said magnets and cores protruding outwardly of said shells, each said shell preventing flux lines between adjacent magnets and cores from interfering with the potential power output thereof.
Claim 5
Dependent Claim
46 words
The electric generator according to claim 1, wherein a plurality of magnetic strips may be embedded within each of said remaining portions, said strips being located in alignment with said facing poles, thereby the magnetic flux lines are guided therealong when passing through said remaining portions.
